This invention relates to windows and doors, and more particularly has reference to the style and rail framing of window sashes and doors.

In the prior art window sashes, doors and the description, wherein reference is made to the accompanying sheet of drawing wherein:

Figures 1 and 2 are sectional views through the frame and sashes in a window with sashes like, one or more surfaces on the metal framing made of metal profiled strips; are visible and exposed to atmospheric influence Fig. 3 is a sectional view of a metal door frame and therefore usually are provided with a resistand ing coating with a neat appearance.

Thus, in production, it is possible the large, plane surfaces of the metal profiled to work continually with treating and/or paintstrips forming the framing by providing them ing of straight lengths of the profiled strips, th grooves which thereupon are bent and further processed. Other features, objects and advantages of the The production in this way will be more rapid present invention will appear from the following and cheaper. With profiled strips shaped accord- 3 ing to Figs. 3 and 4, a very neat appearance is achieved especially in entrances where previous large smooth surfaces have reflected sunshine and daylight and all unevenness of the surfaces have been accentuated in a very non-appealing manner. Toimprove the appearance .of the large surfaces, lines are ruled in the surfaces (Fig. 4). The higher surfaces between the grooves may have the same color as the material or some other color as well as the lower surface parts. The term treatment of a surface here also involves such a production of the profiled strips that the surface is acceptable without any pecial subsequent treatment, which process can be used .in all cases where a sufficiently durable surface is obtained. The figures of the drawing show diagrammatically how th invention can be applied and how the shape of the metal strips may be modified. The profiled strips may have grooves only on one side or on several sides and of course also on the inner sides. It may be suitable to provide grooves only on part of a surface, if just .this part is to be visible in the finished framing. The depth of the grooves as well as their Width may be arranged according to the actual demand. If the lower surfaces are intended to be treated without painting, the depth may be smaller than if they have to be painted.

The invention involves several other advantages among which has to be mentioned that the painting in the lower surfaces in the grooves is protected againstdamage caused by the cleaning or dusting of the framing and the glasses. Venetian blind and other similar arrangements in windows and doors may rub the painted or the treated side. surfaces of the usual frames or sashes, but with framings according to the present invention, this disadvantage is avoided.

For transportation of products of this kind made according to the priorart, it has been necessary to pack them very carefully in order to protect them against scratches. With products according to the present invention, it is possible to reduce considerably the work of packing and the material used therefor without risk.

It is to be understood that the foregoing detailed description ismerely given by way of illustration and many variations may be made therein without departing from the spirit of my invention.

Having described my invention what I desire to secure by Letters Patent is:

1. A metal frame for windows and doors comprising style and rail members, each of said members having front and rear surfaces and a surface extending between the front and rear surfaces and cooperating with the corresponding surfaces of the other members to form an inner peripheral wall defining a light opening, said inner peripheral wall having a glass receiving channel associated therewith extending peripherally of said opening, and the visible surface of said peripheral wall having a plurality of closely spaced peripherally extending parallel grooves to reduce the intensity of light reflected by the visible surface of said wall.

2. A metal frame for windows and doors according to claim 1 in which the lower surfaces of said grooves are painted.

3. A metal frame for windows and doors according to claim 1 in which the glass-receiving channel is positioned adjacent one of said. front and rear surfaces, and further comprising a second sash having a light opening, coupled :to the first-mentioned sash with the light openings in register and disposed against the one of said front and rear surfaces of the first-mentioned sash remote from the glass-receiving channel.

4. A metal frame for windows and .doors according to claim 3 in which the lower surfaces of said grooves are painted.
